Be it .known .that I, THOMAS A. EDISON, a cltizen of the United. States, and'a resident of Llewellyn Park, ange, county of Essex, and State of NewtJersey, have invented certain new and useful Improvements in Bearings, of which the following is a descri tion. 1

y invention relates to bearings fort-he, supporting of shafts driven at high speed." As is well-known, such shafts require very thorough lubrication in order. to reduce thereby avoiding everheating. In the bearing which forms the subject matter of this application, there plied to the shaft for removing oil from t e reservoir and ap lyin it in a continuous stream to the sha an means are also preferably provided for causing the oil to rethat there is a continuous circulation of the same.

Referenceis hereby made to the accom- Figure 1 is a verticlelongitudinal section of a bearing constructed in accordance with my invention, and Fig. 2 is a section on line 22 of Fig; 1. 1

The bearing shown comprises a support ing casing formed of'upper and lower pil-. low blocks I and. 2, secured to ether in any suitable manner, and provi ed on their inner surface or bore with a lining or sleeve 3, of Babbitt metal, or other suitable material. .The pillow blocks 1 and-2 are formed with vertical recesses 5 and Grespectively, and within the same is a ring 7, which is frictionally mounted upon the shaft 8 by means of a plurality of flat sprin plates 9, said plates occupying an interna groove 10- formed within the 'ring 7. The periphery of the ring 7 is formed with shoulders 11, and sloping surfaces 12, which meet at a sharp edge 13. Within the'recess -6 of the upper PlllOW block are a pair of lateral shoulders 14, and at the angles the bases of said shoulders are to the bore Near the I ends of the lining formed at of the bearing.

, what'I c a pair of 3' are circular channels 16, the bottoms of which communicate with vertical channels 17, which lead to the oilreservoir 18, formed in the lower pillow block. Threaded plugs 19 and 2Q may be provided for admitting and drawing ofl oil and for cleaning out the bearing. w hL'IIhe ring 7 is driven by the shaft 8 at a 1 of the shaft; the lower portion of the ring dips into the ,oil a, contained within the reservoir 18 and is coated with the same, and the oil is thrown off by centrifugal action, which is greatly aided by the form of the sloping surfaces 12 and edge 13. The oil is distributed ina shower Qupon the interior of the recess 6, collecting on the shoulders 14, whence it flows down. the channels 15 onto the upper surface of the'shaft 8, and along and around the same, returning to the reservoir 18 through the channels 17 and recess 5'. I have found this bearing to operate successfully without overheating over long periods of time, with shafts driven at aspeed as high as three thousand revolutions per minute. a

Havini;

aim is:-' -1. Thecombination of a shaft, a casing within which said shaft is journaled, a ring and spring plates for frictionally securing said ring to said shaft, said rin being formed with continuouslateral sur aces 12 converging to a sha dips, sybstantially, as set forth.

2. In a device of the class described, the combination of the shaft 8, ring 7 having an annular internal groove 10, andspring plates 9 within said securing said ring tiall as set forth. g
